Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention provides one crimp terminal of the crimp terminal strip for the end of the electric wire.
When continuously crimping while separating each of them, an electric wire end portion identification display tool suitable for being attached to the electric wire end portion, that is, an electric wire, is associated with the crimping operation or before or after the crimping as an independent operation. The present invention relates to a band of an identification display tool.

<Prior Art> A wide range of wiring methods are available in which a large number of electric wires fitted with conductive terminals are collectively attached to a male / female pair of connectors, and simultaneous electrical connection / disconnection of the large number of electric wires is possible. It is being appreciated. In addition, it is often necessary to connect many wires in a complicated state. In these cases, it is widely practiced to attach some kind of mark to each wire end as an identification means for preventing mistakes in the wire connection work, but since it was mostly manual work in the past, it is a huge number. The installation of the identification tool on the end of the wire was extremely complicated and inefficient.

<Problems to be Solved by the Invention> In view of the above situation, the present applicant has filed a patent application for an invention of “method and device for attaching wire end identifier” on December 29, 1991. An electric wire identification indicator suitable for use in the method and apparatus, and in particular, a clearance shape suitable for inserting the indicator holding and expanding holders (11), (11) in the apparatus into the aligned tip end portions. The purpose of the present invention is to provide a large number of electric wire identification indicators connected in a strip shape.

<Means for Solving the Problem> In order to achieve this object, the strip of the electric wire identification and display device according to the present invention is formed from a flexible synthetic resin flat plate-shaped main body portion in the vicinity of both end edges of the rear surface to form a partial arc shape. A pair of projecting pieces having inner surfaces of the projecting pieces are connected in parallel to each other, and the tip edges of the projecting pieces are parallel to each other and substantially parallel to the plate-like body portion. A plurality of display devices, each of which has a clearance between which the width can be reversibly enlarged or reduced, are connected in parallel to each other through a connecting portion in a strip shape, and tongue pieces are provided to project from the outer edge of each connecting portion. It is characterized by

The electric wire identification display tool strip of the present invention is designed so as to facilitate and facilitate the supply to the device of the above-mentioned invention of the present applicant, and the connecting portion between the adjacent display tools is Although it may be a plate-like body which is integral with the plate-like body portion, the central portion may be cut out in a rectangular shape or the like for the reason described later. Further, if the tongue piece projecting from the outer edge of the connecting portion is formed in a square shape, it is convenient because engagement and disengagement of the supply mechanism to the above-mentioned prior application device, for example, with a sprocket-like feeding member are sure.

The pair of the projecting pieces having a partially arcuate inner surface extends over the entire length of the plate-like main body portion on which the identification mark is to be printed, affixed or stamped on the front side, or a length of 1/2 or less thereof. Alternatively, it has a length of 1/2 or more and is projected from the back side of the main body portion.

Further, in the case where the opposed tip edges of the both protruding pieces of each unit display tool form a tapered wide notch region that gradually recedes in a direction away from each other toward the one end side of the clearance, This is convenient because it is easy and sure to insert the display tool holding and expanding holder (11) of the device into the aligned tip portion when loading the device in the prior application.

<Operation> The electric wire identification display device of the present invention is a strip-shaped member, and is configured to be suitable for transportation to the prior application device as described above. Therefore, first, the main parts of the prior application device will be briefly described with reference to FIG. 15. As shown in FIG. 15F, the wire end portion D to which the crimp terminal T is attached is shown in FIG. As described above, it is held on the electric wire mounting table (S) below the device. A pair of swing arms (Y) and (Y) are pivotally attached to the lower part of a reciprocating body (R) that is sandwiched between guide rollers (G) and moves up and down toward the mounting table, and the arms are outwardly directed. They are always biased toward each other and in an open position. However, when the guide roller (G) is in a regulated state ((a) in the figure) and the pair of display tool holding / expanding holders (11) fixedly attached to the lower surface of the arm, the front end portions of the aligned shape are the display. In the state where the tool (H) is thrust into the clearance (4) (described later) and is restrained (FIGS. 8A to 8C), the open posture cannot be taken. That is, as the reciprocating body (R) descends, the electric wire end (D) enters the space between the holders (11) while interrupting, and at that time, the tip end of the holder (11) clears the clearance (4) of the display tool (H). ), The wire end (D) reaches the bottom of the wire receiving recess of the display (H), and then the reciprocating body (R) descends slightly against the elasticity of the spring (B). In the state of (d), the protruding piece (2) (described later) applied to the arm (11) is released from the high speed, and the arm retracts to the side. At the same time, since the projection itself of the display tool (H) is also restored to the original posture and the clearance is also restored to the original width, the display tool is extended to the electric wire end portion in a state of enclosing substantially the entire circumference of the electric wire end portion. Will be installed. Thus, the end of the electric wire as shown in the same figure (g) with the display tool (H) attached is left on the electric wire mounting table (S),
Next, when the reciprocating body (R) starts to rise as shown in FIG. 8 (e), the wire end is ready to be taken out of the device, while the guide roller (G) again causes the swing arm (Y) to move. Is returning to the closed posture due to regulations, while the same figure (a)
Return to the state of.

Since the electric wire identification indicator constituting the strip of the present invention is used in the prior application method and apparatus as outlined above,
A flat plate-shaped main body made of a flexible synthetic resin, which is continuous from the vicinity of both end edges of the back surface and has inner arc-shaped surfaces and is parallel to each other 1
The reversibly widenable clearance formed between the tips of the pair of projecting pieces in parallel to the plate-shaped main body is
The width in a normal state where external force is not applied is made as narrow as possible, and moreover, the thickness of the aligned tip portions of the holding and expanding holder (11) for the pair of display devices fixed to the lower surface of the device swing arm. Again, the structure is related to the fact that it is made thin enough correspondingly.

That is, the width of the holder (11) is narrow in the direction parallel to the aligned front end portion, that is, in the direction of the axis of the recess for accommodating the electric wire end portion provided in the display tool (direction perpendicular to the paper surface in FIG. 15A). When the clearance is inserted into the thin-walled holder-shaped tip portion, the tapered wide width is formed such that both tip edges on one end side of the clearance gradually recede in the direction away from each other toward the one end. The notch area acts as a guide portion for the insertion and facilitates the insertion operation.

Moreover, since the tapered wide notch region stops near the edge of the clearance and is shorter than the entire length of the clearance, there is no fear of impairing the force of attaching the display tool to the end of the wire.

The above is a description of the display device as a single body which constitutes the band-shaped body in advance. The action of the band-shaped body itself peculiar to the present invention is as follows.

That is, a pair of sprocket wheel-like feed mechanisms (not shown) repeatedly engage and disengage from the tongues projecting at regular intervals along both outer edges of the strip, while the arrows in FIG. The strip is supplied to the prior application device in the (Z) direction. At that time, since the tongue pieces are rectangular and are arranged at both outer edges of the left and right sides, these two rows of tongue pieces are accurately engaged with and disengaged from the sprocket wheel-shaped feed members, respectively, and thus cause skewing and the like. There is no fear. After the plate-like body portion (1) is printed with, for example, an alphanumeric type identification symbol (9) in the process of feeding into the above device, along the cut lines (C) and (C) in FIG. Cut one by one, then 16th
It is inserted into the device in the direction of the arrow (X) in FIG. If a rectangular cutout is provided in the connecting portion where the tongue piece is projected, it is possible to cut along the short cut line (C) leading to the cutout while avoiding the tongue piece, so that the cutting is easy.

Furthermore, it is worth noting that since the tongue piece is provided at the connecting portion, the tongue piece is automatically cut off at the same time as the connecting portion when the single piece is cut off. However, there is no possibility of adversely affecting the use and operation of the wire identification device as a single unit.

<Embodiment> An illustrated embodiment will be described below with reference to Figs.
In this wire identification indicator (H) made by injection molding using polypropylene in the first embodiment of the figure, the flat plate-shaped main body portion (1) has a partial arc-shaped inner surface from the vicinity of both end edges of the back surface. A pair of projecting pieces (2) having parallel lines are provided in parallel with each other, and the tip edges (3) and (3) of the projecting pieces (2) are parallel to each other and with respect to the plate-shaped main body portion (1). However, a clearance (4) capable of widening is formed between the two leading edges (3) and (3), and both leading edges (3) on one end side of the clearance (4) are formed. , (3) gradually recedes in a direction away from each other as they go toward the one end, forming a tapered wide notch region (5).

As shown in FIG. 2, the electric wire identification indicating tool (H) is connected in a large number in parallel with each other through the connecting portions (6), (6) arranged near both ends to form a strip shape. It is supplied to the above-mentioned prior application device in the direction of arrow (Z) in Fig. (A), and in the process, for example, an alphanumeric type identification symbol (9) is printed on the surface of the plate-shaped main body portion (1), Cut one by one along the cutting lines (C) and (C) in FIG.
It is inserted into the device in the direction of the arrow (X) in FIG. Specifically, as described above, the aligned tip end portion of the holder (11) as shown in FIG. 15 (f) is tightly fitted into the clearance (4). At this time, the tapered wide notch region (5) on the one end side of the clearance acts as a guide portion, and the fitting can be performed easily and reliably. The contents of the subsequent operations are as already described in the <action> column, and the display tool is finally attached to the end of the electric wire in the direction of the arrow (F) in FIG.

A tongue piece (7) is projected from the outer edges of the pair of facing connecting portions (6) and (6), which is accurate when supplying the belt-shaped body to the device. The rectangular notch (8) between the connecting portions (6) and (6) not only saves material but also cuts at the cut line (C) shown in FIG. 2. It has the effect of facilitating.

Further, the protrusion (2) has a shape in which it gradually transitions from the base portion (2a) in which the inner diameter of the inner surface of the partial arc shape is increased to the extension portion (2b) of the small inner diameter. This is in consideration of the fact that the cylindrical portion (T ') of the crimp terminal (T) fixed to () is larger than the outer diameter of the wire. In the first embodiment, the length of the extension portion (2b) is about 1 of the "remaining" length of the plate-shaped main body portion (1) when the length corresponding to the base portion (2a) is disregarded. The composition has reached to / 2. As a result, it is possible to maintain sufficient flexibility of the wire end portion in the vicinity of the wire identification indicator (H) and also to secure the fixing strength of the display tool to the end portion.

FIG. 5 to FIG. 6 show a single display device having a shape suitable for use in a case where the flexibility of the electric wire end portion near the display device (H) is particularly desired. That is, the extension portion (2b) is made extremely short, and the length of the "remaining" portion of the plate-shaped main body portion (1) is about the same.
Although it ends at about 1/5, the tongue and other points are the same as those in FIG.

On the contrary, FIGS. 7 to 9 show a shape suitable for use in the case where the flexibility of the wire end portion near the display tool (H) is not so desired, and rather the strong mounting of the display tool is strongly desired. Shows a single display device. The extension portion (2b) has a length over the entire length of the plate-shaped main body portion (1), but is configured as a strip-shaped body,
That is, the tongue and other points are the same as those in FIG.

On the back surface of the plate-shaped main body portion (1), the protrusion (1a) protruding at the location of the base (2a) is engaged with the pressure-bonding concave portion of the cylindrical portion (T ') of the pressure-bonding terminal (T). In this case, the display tool (H) is prevented from falling off.

In the second embodiment shown in FIGS. 10 to 14, the display device (H) connected in the required number of strips is used under the same conditions up to the last one.
In order to supply in the direction of the arrow (Z) in FIG. 16 (a), an ear-shaped extension (10) is additionally extended from the terminal display tool via the connecting portions (6), (6). The width of the ear-shaped extension (10) is the same as the length of each indicator (H), and the vertical bent portion (at the same height as the protruding piece (2) from both end edges to the same side as the protruding piece (2)). 10a) are installed in a row. Therefore, even when the last display tool forming a strip is cut off, the strip can be securely held in the supply mechanism for the prior application device without any fear of causing vertical, horizontal, or horizontal fluctuations. it can. The other points are the same as those in the first embodiment.

Various modifications to the above-mentioned invention of the present application, for example, if the tongue piece (7) is erected vertically to the connecting portion (6) and on the side opposite to the protruding piece (2), only one wide sprocket is provided. Therefore, there is an advantage that it can be sent to the above device. still,
With respect to the display unit alone, the inner and outer diameters of the partial arcuate inner surface of the protruding piece (2) are made uniform over the entire length, and when the tubular portion of the crimp terminal is pre-wrapped with a resin coating, the tubular portion is mounted avoiding the tubular portion. Or a tapered wide cutout area is provided at both ends of the clearance so that the display tool holding / expanding holder (11) of the prior application device can be installed in either forward or reverse direction.
It is also possible to adopt a configuration such that it can be inserted into the aligned tip end portion of (11).

<Effects of the Invention> According to the present invention, a projecting piece having a shape capable of surrounding and flexing substantially the entire circumference of the wire end is projectingly provided from the plate-shaped main body part, and the width between the tip edges thereof is the minimum necessary. Provided is a band-shaped body in which a large number of display units each having a narrow and reversibly expandable / reducible clearance are continuously arranged in a band shape and tongue pieces are arranged in rows at both outer edges thereof. Therefore, the appropriate sprocket-like feeding member allows the belt-like body to be moved straight forward without fear of skewing, which enables reliable supply to the above-mentioned prior application device and contributes to an improvement in the efficiency of the work of mounting the display tool in the device. The place is huge.

Furthermore, it is worth noting that since the tongue piece is provided at the connecting portion, the tongue piece is automatically cut off at the same time as the connecting portion when the single piece is cut off. However, there is no possibility of adversely affecting the use and operation of the wire identification device as a single unit.

In this way, the electric wire identification display tool having a simple structure in which only a pair of projecting pieces is extended from the back surface of the flat plate-shaped main body portion is continuously connected in a strip shape, and the tongue pieces are projected from both side edges. According to the belt-shaped body of the present invention, despite the extremely simple structure,
An indicator for identifying a number of complicated wire ends can be attached to the surface of the plate-shaped main body part, and then the display unit can be steadily and efficiently attached to the wire end, and its practical value is great. is there.
